Summary
Chronic visceral pain is a common and debilitating condition arising from numerous diseases that affect our internal organs. There is a desperate need for more information about the mechanisms responsible for signalling chronic visceral pain to provide therapies and potentially find a cure for it. Our research focuses on ?-conotoxins (small peptides from marine cone snail venom) as novel potential therapeutic agents for the treatment of chronic visceral pain.

Summary
Obesity is a common and burdensome health problem in the community which leads to diabetes and heart disease. A number of factors, including hormones play important roles in determing risk of obesity. This study proposes to investigate whether the Ski gene which is a regulatory factor for many hormones affects metabolism in transgenic mouse models of altered Ski function. The proposed studies may identify Ski as a target for therapy for obesity and improvement in sketal muscle metabolism.

How blood vessel stiffness regulates their growth and maintenance. This project aims to reveal an unidentified molecular mechanism of how endothelial cells in the walls of blood vessels detect stiffness of the surrounding environment in order to regulate blood vessel growth and maintenance. The results are expected to advance the emerging field of mechanobiology by combining cutting-edge cell biology and microscopy techniques carried out in novel 3D cell culture and unique quail models.

This project aims to reveal an unidentified molecular mechanism of how endothelial cells in the walls of blood vessels detect stiffness of the surrounding environment in order to regulate blood vessel growth and maintenance. The results are expected to advance the emerging field of mechanobiology by combining cutting-edge cell biology and microscopy techniques carried out in novel 3D cell culture and unique quail models. The benefits of these outcomes include generation of knowledge on the impact of tissue stiffness on the signalling mechanisms that drive formation and maintenance of blood vessels. In the long term, this fundamental understanding could give rise to major developments in emerging industries such as organ bioengineering.Read moreRead less

Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D.

Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less

How does heme regulate blood vessel formation in the brain? There are more than 600 kilometres of blood vessels in the brain, all of which are lined by tightly packed cells that protect the brain from toxins. My research aims to investigate how these blood vessels are formed.

My research aims to investigate how these blood vessels are formed. This project expects to reveal the role that a critical signalling molecule called heme plays in this fundamental biological process. I will use cutting-edge structural biology and biophysical techniques to uncover the molecular mechanisms that allow heme to enter cells and regulate blood vessel growth in the brain. The outcomes of this research will enhance our understanding of the brain’s core infrastructure and will contribute to an understanding of how cerebral blood vessels grow and maintain integrity.

This project aims to establish a high-throughput, automated patch clamp facility to enable research at the forefront of cell phenotyping and drug discovery. Ion channels are membrane proteins that underlie cell function and are therefore important drug targets. The patch clamp technique is the most powerful tool available to functionally characterise cells and study the function of ion channels. The significant advance provided by the high-throughput, automated patch clamp system is that it allows up to 384 cells to be recorded simultaneously. This project expects to enhance capacity to automate and standardise the quality of recordings, substantially increase the rate of data production, and enable greater access to patch clamp technology.Read moreRead less
